Application filed May 12, 1900- T0 at whom it may concern:

Be it known that I, JOHN NAGELDINGER, a citizen of the United States,residing in New York, borough of Manhattan, State of New York, haveinvented certain new and useful Improvements in Apparatus for DrawingEffervescent Liquids, of which the followingis a specification.

This invention relates to improvements in apparatus for drawing offliquids under pressure of carbonic-acid gas without the excessivefoaming which occurs when the liquid is drawn off directly fromthefountain, the ob ject of the invention being to provide an apparatusin which the manipulations of supplying the carbonated beverage from thefountain to a pressurerelieving chamber, the discharge of the excess ofgas from said chamber, and the drawing off of the beverage areaccomplished by simple and easilymanipulated devices; and the inventionconsists of an apparatus for drawing effervescent liquids, whichcomprises a pressure-relieving chamber, a socket for supporting saidchamber, the socket being provided with a supplychannel, apressure-relieving channel, and a discharge-channel, a valvedsupply-pipe connected with the supply-channel, a pressure: relievingvalve, a spindle for operating said pressure-relieving valve, a.valvechamber inclosing said pressure-relieving valve and provided with adischargetube extending upwardly into the pressure-relieving cham-' berabove the level of the carbonated liquid in the same, a liquid-dischargevalve, a stationary handle on the socket of the pressurerelievingchamber, an auxiliary handle below the same for operating thepressure-relieving and liquid-discharge valves, and a lever foroperating the supply-valve, as will be fully described hereinafter andpointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved apparatus for drawing efiervescent liquids.

Fig. 2 is a front elevation of the same. Fig. 3 is a horizontal sectionon line 3 3, Fig. 1. Fig. 4 is a vertical longitudinal section on line 44:, Fig. 2, drawn on a larger scale. Fig. 5 is a detail vertical sectionof the reliefvalve for discharging the surplus gas from thepressurenrelieving chamber, drawn ona Serial Nb. 16,410. the model.)

still larger scale. Fig. 6 is a vertical longitudinal section showingthe gas-relief valve of the pressure-relievingcham ber in position fordischarging the surplus gas from said chamber. Fig. 7 is asimilarsection showing the gas -relief valve and liquid -discharge valvein open position for discharging the carbonated beverage from saidpressure-relieving chamber. Figs. 8 and 9 are horizontal sections online 8 8, Fig. 4, showing the supply-valve respectively in closed andopen position, so as to interrupt or permit the supply of carbonatedliquid from the fountain to the pressure-relieving chamber.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a pressure-relieving chamber,which is preferably made of glass of suitable thickness so as to resistthe pressure of the effervescent liquid that is to be supplied to anddrawn off from the same. The pressure-relieving chamber A is preferablymade of a rounded shape at its upper closed part and provided with acylindrical neck, which is supported in a socket A, the lower end of theneck resting on an elastic packing-ring a, that is seated in an annularrecess in the bottom of the socket A. The lower end of the neck of thepressure-relieving chamber A is made thicker, so as to form a rim 0.,which is engaged by a split annular screw-nut A that screws by itsexterior screw-thread into the interiorlythreaded socket A, so as tohold the neck of the pressure-relieving chamber A tightly in connectionwith the elastic packing a.

The rear part of the socket A is connected by a valved supply-pipe Bwith the vessel or fountain containing the carbonated liquid underpressure. In the bottom of the socket A are arranged two verticalchannels d and 01 the channel (1 communicating with the supplypipe B,while the central channel d communicates with a discharge-spout D, whichis screwed into the front part of the socket A diametricallyin line withthe supply-pipe D. The bottom of the socket A is provided at rightangles with the supply-pipe B and the discharge-spout D with ahorizontal stationary handle H, while at a point diametrically oppositethereto are arranged two lugs h h, which are connected by a pivot-link hwith 7 eeossi the end of the second fulcrumed handle H, which isprovided with a circular enlargement that extends around a cylindricalcasing H which slides on the cylindrical neck A of the socket A. Thecircular enlargement of the lower handle H is fulcrumed by diametricalpivot-screws h to the casing H the handle H being located verticallybelow the stationary handle I-I, so that when the palm of the hand restson the stationary handie the fingers can readily grasp the lower handleH, and thereby lift it in an upward direction toward the stationaryhandle H.

In the neck A of the socket A is guided a spindle E, which is screwedinto the bottom of the casing H and is held in position therein by ajam-nut e. The upper end of the spindle E carries a valve E, whichpresses on a seat at the upper end of a tube Ehwhich is attached intothe bottom of a cylindrical valve-chamber F, located in the neck of thepressure-relieving chamber A. The bottom of the valve-chamber F isprovided at its under side with an elastic gasket F,that rests on acircular valve-seat f at the upper end of the central channel (1 of thesocket A, while the upper tapering end of the valvechamber F is providedwith a tube f which extends centrally through the pressure-relievingchamber above the level of the liquid in said chamber, the upperinteriorly-threaded end of the valve-chamber being screwed onto thebottom portion of the same, as shown clearly in Fig. 5. The lower partof the spindle is made solid, while the upper part is made tubular bymeans of a central bore, the upper end of the spindle being providedbelow the valve E with several transverse holes 0, while the lower endof the bore is also provided with transverse holes 0, which communicatewith the hollow space around the spindle and from there with a smallgasrelief spout D, which is located below the liquid-discharge spout D,as shown in Fig. 4:.

The valve E is provided with several upwardlyrprojecting lugs e, thatabut against the upper end of the valve-chamber F, so as to lift thevalve-chamber when the spindle E is lifted by the handle H and producethereby, first, the opening of the gas-relief valve and then the openingof the liquid-discharge valve F, as shown in Figs. 6 and 7. A helicalsprings is interposed between the bottom of the cylindrical casing H anda washer g, which is pressed against an interior shoulder g, an elasticpacking being interposed between the washer g and shoulder g. Thetension of the spring 3 holds the gas-relief valve, as well as theliquid discharge and supply valve, normally in a closed position whenthe lower handle H is not lifted. When the handle H is lifted, thecasing H slides in upward direction on the neck A of the socket A, itbeing provided with a vertical recess g for clearing the auxiliarygas-discharge spout D, the lifting of the sliding casin g H? and spindleE producing successively shorter arm of an elbow-shaped lever H which isfulcrumed to a horizontal lug b of the valve-casing, the longer arm orhandle of the elbow-shaped lever being arranged parallel with and on alevel with the stationary handle H, as shown clearly in Figs. 1 and 3.The rear end of the supply-pipe B is coupled with a pipe leading to thefountain containing the carbonated liquid to be dispensed.

When the proper connection with the fountain is made, rnyimprovedapparatus for disposing the eifervescent liquids is operated as follows:The tumbler or other vessel into which the carbonated beverage is to bedischarged is held in the left hand, while the right hand is used foroperating the apparatus. For this purpose the palm of the right hand isplaced on the stationary handle H, so that the fingers can grasp thehandle of the main supply-valve and move the same toward the station aryhandle. This opens the supply-valve B against the tension of its spring,so that immediately a supply of carbonated liquid from the fountain isdelivered through the connecting-channel in the valve-casing and thechannel d in the socket A to the pressure-relieving chamber, in whichthe liquid rises to such a level until the equilibrium of pressure inthe pressure-relieving chamber and the fountain is established. As soonas the pressure-relieving chamber is filled to this extent the handle Hof the su p pl y-valve is released and the auxiliary handle H grasped bythe fingers, so as to produce the lifting of the same. This produces thelifting of the cylindrical casing H on the neck of the socket A and thelifting of the spindle E against the tension of the spring 3, so thatfirst the gas-relief valve at the upper end of the spindle is liftedaway from its seat, as shown in Fig. 6, and thereby the connectionbetween the space above the liquid in the pressure-relieving chamber,the hollow upper end of the spindle, the interior of the valve'ch amber,and the gasdischarge spout is obtained and an immediate discharge of thesurplus gas in the pressurerelieving chamber is produced. By continuingthe lifting of the auxiliary handle, valvecasing, and spindle theupwardly-projecting lugs at the upper end of the gas-relief valveabut'against the upper part of the valvechamber F and produce thelifting of the same, so that the liquid-discharge valve in the neck ofthe pressure-relieving chamber is moved away from its seat, and therebya connection between the neck of the pressurerelieving chamber, thechannel (Z and the discharge-spout D is established, so that thecarbonated liquid can be drawn off from the pressure-relieving chamberwithoutexcessive foaming into the glass or vessel held below the spout.During the drawing off of the carbonated liquid from thepressure-relieving chamber the air is permitted to pass through theauxiliary spout D, the neck of the socket A, the central bore of thespindle, valve-chamber, and the discharge-tube, so that atmosphericpressure is established in the upper part of the pressure relievingchamber and the free drawing off of the carbonated liquid into a tumbleror vessel obtained. The blowing off of the surplus gas through theauxiliary spout and the discharge of the carbonated liquid take place inquick succession, as the upward motion of the auxiliary handle producesthe opening of the gas and liquid discharge valves, the escape of gasbeing indicated by a slight noise, which takes place immediately beforethe flow of the liquid from the dischargespout. When it is desired tointerrupt the discharge of the efiervescent liquid, the auxiliary handleis released, so that the gas relief and discharge valves are immediatelyreturned by the tension of the spring on the sliding casing H to theirclosed positions on the respective valve-seats and the discharge of theliquid interrupted.

As the supply of the carbonated liquid to the pressure -relievingchamber is accom plished by one lever and the discharge of thecarbonated liquid by a second lever, no possible mistake in operatingthe device can occur. The actuation of one lever produces immediately asupply of carbonated liquid, while the actuation of the other leverproduces the discharge of the same. As the hand always rests on thestationary handle when operating either the handle of the supply ordischarge valve, the drawing off of the carbonated liquid from thefountain is accomplished in a very convenient and certain manner withoutany excessive foaming of the liquid.
